yarn-outdated-formatter

A CLI tool that formats the JSON output from `yarn outdated --json` into human-readable or machine-parseable formats such as markdown, JSON, CSV, or Mackerel service metrics. v4.0.0 is the current stable release. Compared to manual parsing, it provides a structured, configurable output with support for excluding packages and linking changelog URLs. It also works with `npm outdated --json --long` with reduced functionality. Designed for CI/CD pipelines and dependency management automation.
